Effect of the ADRB1 1165C>G and 145A>G polymorphisms on hemodynamic response during dobutamine stress echocardiography.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe aim of this study was to determine an association between the ADRB1 1165C>G and 145A>G polymorphisms and hemodynamic response [heart rate (HR), systolic (SBP) and diastolic (DBP) blood pressure] to dobutamine during dobutamine stress echocardiography (DSE).
methodsThe study involved 144 patients with clinical indications for DSE. The PCR-restriction fragment length polymorphism method was used to identify the ADRB1 1165C>G and 145A>G polymorphisms.
resultsHeart rate during DSE increased in all analyzed study groups. Patients with the ADRB1 1165CC and 1165CG+GG polymorphisms demonstrated similar HR, including magnitude of response [change in heart rate (ΔHR 0-30): 42.1 ± 17.5 vs. 46.1 ± 15.5 bpm, respectively]. HR and ΔHR 0-30 were comparable in ADRB1145AA and 145AG subjects in the course of DSE. SBP and DBP at all stages of DSE were similar in subjects with either polymorphism and did not differentiate patients with the ADRB1 145AA polymorphism from those with the ADRB1 145AG polymorphism, nor those with the ADRB1 1165CC polymorphism from those with the ADRB1 1165CG+GG polymorphism. No differences were noted in the magnitude of response, with the increase in SBP and DBP comparable in all genotypes. Similar observations were made in patients (25/144 studied) with atropine requirements during DSE.
conclusionThe ADRB1 1165C>G and 145A>G polymorphisms are not associated with the HR, SBP and DBP responses in Polish Caucasian patients requiring diagnostic dobutamine stress echocardiography.
